Description
Technical field
It is especially a kind of for producing the crystallisation by cooling kettle of o-cyanobenzyl chloride the present invention relates to crystallization kettle apparatus field.
Background technique
Currently, o-cyanobenzyl chloride is a kind of irritant smell, the colourless acicular crystals to jade green, be soluble in ethyl alcohol,
The organic solvents such as chloroform, acetone, toluene, sterling fusing point are 59.5 DEG C, belong to a kind of organic synthesis intermediate, are mainly used for closing
At diphenyl ethylene fluorescent bleaches, such as fluorescent whitening agent ER series.
O-cyanobenzyl chloride product can also generate large quantity of exhaust gas during crystallization kettle crystallizes, and the constituent of exhaust gas is main
Including the complete chlorine of unreacted, o methyl benzonitrile material and HCl gas etc., these exhaust gas are usually to pass through chlorination kettle top
The delivery pipe in portion is directly discharged to outside, and exhaust gas is cooled during passing through delivery pipe and is easy the fouling in tube wall, the row of causing
The blocking of pipe is put, and delivery pipe makes in crystallization kettle once blocking, the exhaust gas that the interior reaction of crystallization kettle generates cannot timely be discharged
Pressure becomes larger, and influences production quality, also brings some potential safety problems to the normal crystallization production of crystallization kettle.
Summary of the invention
It is deposited during crystallization kettle is crystallized and produced present invention aim to solve current o-cyanobenzyl chloride product
The above problem, provide thus a kind of for producing the crystallisation by cooling kettle of o-cyanobenzyl chloride.
Concrete scheme of the invention is: it is a kind of for producing the crystallisation by cooling kettle of o-cyanobenzyl chloride, there is autoclave body, outside autoclave body
Wall is set with the collet for containing brine ice, and cryosel water inlet and cryosel water out are respectively equipped on collet；On autoclave body top
Portion is equipped with feed inlet and waste gas outlet, and autoclave body bottom is equipped with discharge port；It is characterized in that: fixing seat is equipped at the top of autoclave body, solid
Stirring motor and matched reduction gearbox are housed in reservation, the output end connection of reduction gearbox stretches to the intracorporal shaft of kettle, and
Agitator arm is housed in the bottom end of shaft；Control valve is respectively arranged on pipeline where the inlet port and outlet port；The exhaust gas
Waste gas purification apparatus and condensing unit are sequentially arranged on pipeline where exporting；Observation panel is additionally provided on the autoclave body.
Heretofore described condensing unit has the tubular condensing cover being set on the pipeline of waste gas outlet place, tubular cold
Spiral water-cooling is equipped in the housing of solidifying cover, it is tubular cold that the top and bottom nozzle of the spiral water-cooling seals stretching
Outside solidifying cover housing, and water inlet pipe and outlet pipe have been respectively communicated with it.
The configuration of the present invention is simple, ingenious in design, crystalline rate is high, effectively eliminates exhaust gas in its delivery pipe inner pipe wall
There is a phenomenon where foulings, also ensure the safety of crystallization production.
